Chlorine Dioxide
Описание: Chlorine Dioxide Chlorine dioxide (ClO2) is a chemical compound consisting of one chlorine atom and two oxygen atoms. It is a reddish to yellowish-green gas at room temperature that dissolves in water. It is used for a variety of antimicrobial uses, including the disinfection of drinking water. Chlorine dioxide gas is usually produced onsite from sodium chlorate or sodium chlorite. Uses & BenefitsPowerful Disinfection in Water TreatmentChlorine dioxide is a disinfectant. When added to drinking water, it helps destroy bacteria, viruses and some types of parasites that can make people sick, such as Cryptosporidium parvum and Giardia lamblia. The Environmental Protection Agency (EPA) regulates the maximum concentration of Chlorine Dioxide Tablets in drinking water to be no greater than 0.8 parts per million (ppm). Industrial/Manufacturing UsesChlorine dioxide chemistry is used in a wide variety of industrial, oil and gas, food and municipal applications: Food and Beverage Production Chlorine Dioxide Powder can be used as an antimicrobial agent in water used in poultry processing and to wash fruits and vegetables. Paper Processing Chlorine dioxide is used to chemically process wood pulp for paper manufacturing. Medical Applications In hospitals and other healthcare environments, chlorine dioxide gas helps to sterilize medical and laboratory equipment, surfaces, rooms and tools. Researchers have found that at appropriate concentrations, chlorine dioxide is both safe and effective at helping to eliminate Legionella bacteria in hospital environments. Legionella pneumophila bacteria can cause Legionnaires’ disease, a potentially deadly type of pneumonia. Chlorine dioxide is not a cure or treatment for medical ailments, including but not limited to autism, HIV, malaria, hepatitis viruses, influenza, common colds, and cancer. Claims that the ingestion of chlorine dioxide, often advertised as “Miracle Mineral Solution” or MMS, will cure these or other ailments are false. Safety InformationChlorine Dioxide Liquid is used to disinfect drinking water around the world. According to U.S. Centers for Disease Control and Prevention, chlorine dioxide is added to drinking water to protect people from harmful bacteria and other microorganisms. EPA recognizes chlorine dioxide use as a drinking water disinfectant, and it is included in the World Health Organization’s (WHO) Guidelines for Drinking-water Quality. In its pure form, chlorine dioxide is a hazardous gas but most people are “not likely” to breathe air containing dangerous levels of chlorine dioxide as it rapidly breaks down in air to chlorine gas and oxygen. For workers who use chlorine dioxide, the U.S. Occupational Safety and Hazard Administration (OSHA) regulates the level of chlorine dioxide in workplace air for safety. OSHA has set a Permissible Exposure Limit (PEL) for chlorine dioxide at 0.1 parts per million (ppm), or 0.3 milligrams (mg) per cubic meters (m3) for workers using chlorine dioxide for general industrial purposes. OSHA also has a PEL for chlorine dioxide for the construction industry. Air Disinfection Gel is one powerhouse sanitizer that is getting more attention recently as food processors look for more efficacious products to help them win the sanitation battle. Approved by the U.S. Food and Drug Administration (FDA) and the U.S. Environmental Protection Agency (EPA), it is as powerful as peracetic acid and more economical, yet it has far less of an impact on the environment than quaternary ammonium salts, chlorine or bromine, making it an excellent choice for food processing plants. It costs about the same to use as other sanitizers but is more versatile and less harmful. It’s also been shown to destroy and prevent biofilms, one of the biggest challenges to food processors in destroying harmful bacteria. It also does not have the strong odor or corrosive qualities associated with chlorine. It is a versatile alternative that can be used in many sanitation applications, including pasteurization equipment, heat exchangers, cooling towers, hard surface disinfecting, potable water treatment and deodorizing stacks in rendering plants. It is already growing in popularity as a tool to control microbiological growth in the dairy industry, the beverage industry, the fruit and vegetable processing industries, canning plants, and in poultry and beef facilities. Sodium Dichloroisocyanurate is the sodium salt of a chlorinated hydroxytriazine and is used as a source of free available chlorine, in the form of hypochlorous acid, for the disinfection of water. It is widely used as a stable source of chlorine for the disinfection of swimming pools and in the food industry. It is also used as a means of disinfecting drinking-water, primarily in emergencies, when it provides an easy-to-use source of free chlorine, and, more recently, as the form of chlorine for household point-of-use water treatment. Disinfectant Wipes should never be reused. Reusing wipes will move germs from one surface to another, which is potentially harmful in the current pandemic. In order for any surface to be properly disinfected, the U.S. CDC recommends following the instructions on each product carefully and leaving the disinfectant on the surface for 3-5 minutes. This means the surface needs to be wet for this period of time, and you may need to use more than one disinfectant wipe depending on the size of the surface. However, you should never reuse the same disinfectant wipe.

Airless Spray Paint Application for Piping and Equipments
Описание: Airless Spray Paint Application for Piping and Equipments Airless spray application shall be in accordance with the following procedure:as per steel structure paint Manual Vol.1 & Vol.2 by SSPC, USA, Air less spray relies on hydraulic pressure rather than air atomization to produce the desired spray. An air compressor or electric motor is used to operate a pump to produce pressures of 1000 to 6000 psi. Paint is delivered to the spray gun at this pressure through a single hose within the gun. A single paint stream is divided into separate streams, which are forced through a small orifice resulting in atomization of paint without the use of air. This results in more rapid coverage with less over spray. Airless spray usually is faster, cleaner, more economical and easier to use than conventional air spray. Pipe Spray Painting Machine is mounted on wheels, and paint is aspirated in a hose that sucks paint from any container, including drums. The unit shall have inbuilt agitator that keep the paint uniformly mixed during the spraying. The unit shall consist of inbuilt strainer. Usually very small quantities of thinning are required before spray. In case of High Build Epoxy coating (two pack). 30:1 pump ratio and 0.020-0.023” tip size will provide a good spray pattern. Ideally fluid hoses should not be less than 3/8” ID and not longer than 50 ft to obtain optimum results. In case of gun choking, de-choking steps shall be followed immediately. What Are Spray Painting and Powder Coating? Spray Steel Pipe Painting Production Line is the process of applying liquid paint using pressure. This can be done in one of three ways:Conventional high-pressure sprayingAirless spraying High-volume low-pressure (HVLP) spraying Conventional High-Pressure Spray Painting This method uses an air compressor and an air gun. When the gun's trigger is pressed, the paint m The air gun is usually held about 6 to 10 inches from the object being painted and moved back and forth over the surface to ensure an even and continuous coat. Airless Spraying Systems These Steel Pipe Spraying Coating Machine systems use a high-pressure pump, which can range in pressure from just 300 to 7,500 pounds per square inch, depending on the application. Laser marking works by using a focused beam of light to mark the surface of a material. When the beam interacts with the material’s surface, it alters the material’s properties and appearance. This concentrated beam targets only a specified area, allowing the laser Automatic Marking Machine to create precise, high quality, high-contrast marks that are easy to read or scan on virtually any surface. This feature makes laser marking ideal for applications where accuracy and permanency are critical to success. There are several types of laser marking systems, and each operates slightly differently. The correct process to use the machine also depends on the material you’re working with and the application you’re using. MECCO offers a list of resources to help you operate your machine and troubleshoot any issues, from how-to videos to detailed documentation. When using any laser marking machine, it’s important to follow all safety guidelines. Thanks to a variety of preventative measures, including safety enclosure options, laser marking is a relatively safe process.

Lapping Machines Process
Описание: Lapping Machines Process Lapping Machines are a type of precision finishing machine. Lapping is a loose abrasive machining process that differs from honing or grinding because the abrasive action comes not from a solid abrasive (like a grinding wheel) but from a slurry--abrasive particles mixed with oil or water. The slurry forms an abrasive film between the underlying lapping plate and the parts to be lapped. The part stock is gradually removed through the rolling and sliding action of the abrasive grains between the lapping wheel and the workpiece. The slurry, along with the removed stock, drains away from the table. Lapping machines create truly flat surfaces--normally up to 0.001mm, with surface finishes of better than Ra.01. Overall, lapping produces extreme dimensional accuracy, corrects minor imperfections of shape, refines surface finish, and produces close fit between mating surfaces. Lapping machines may be beneficial whenever absolute flatness, parallelism, or surface finish is essential. Since it is a loose abrasive process, irregularly-shaped or non-magnetic parts can be easily accommodated. Lapping removes stock quickly, with no clamping or heat distortion, no expensive tooling required, and virtually no maintenance. Inspection and production costs are also lower, since the machine can be run by semi-skilled operators. Parts can be run as easily in small batches as in production processes. How does it work?Flat Lapping Machines consist of 5 parts: the rotating table (called a lapping plate), several conditioning rings, the topweight, the slurry, and the machine itself. The machine houses the controls, engine, coolant, filter, and other subsidiary components for proper operation of the mechanism. The lapping plate is the only thing that is turned by the motor--the conditioning rings turn automatically as the plate itself turns. The plate is usually made of high-quality soft cast iron, though copper and other soft metals may also be used. It may be anywhere from 12 to 144 inches in diameter and feature spirals, cross-hatches, rings, or other shapes. The conditioning rings function as the workholding device. These rings distribute the wear evenly across the lapping plate increasing its life, while also holding the workpiece in place. Special rings may be fitted for cylindrical or especially long pieces. A top plate presses the pieces down in order to ensure abrasion occurs. These may be simple lids or mechanically operated piston-like covers.A slurry made by combining various abrasive materials such as diamond or carbon with a liquid base like oil or water is fed between the lapping plate and the top plate, and distributed evenly across the surface by the plate's rotation. The tiny abrasives suspended in the liquid drag and tumble across the surface of the held pieces, grinding away at any micro-irregularities in the part's surface. The Polishing Machine (also called the Buffing Machine) is used to polish soft metals including copper and brass as well as plastics such as perspex. The two ‘mops’ spin at high speed when the ‘on’ switch is pressed. If the material is carefully pressed against the mop and moved backwards and forwards it will be polished. The material must be filed to removed scratches and then wet and dry paper or emery cloth is used to further smooth the surfaces. Only then can it be polished on the buffing machine. There are many types of involved equipment in the wire drawing machine industry, the common Wire Drawing Machine has a water tank type drawing machine, straight wiredrawing machine, the pulley type drawing machine, inverted vertical drawing machine, and so on. Drawing machine is mainly used in the processing of copper wire, stainless steel wire and other metal wire and cable materials, belonging to the important processing equipment in the cable manufacturing industry. Drawing: drawing process is the most important work segment for wire drawing machine. Different metal material, silk varieties and different requirements, will have different drawing process, the end of the article will detail the water tank draw machine and straight wire-drawing machine specific operation process; Wire: the take-up links work speed determines the whole drawing machinery production efficiency, is the most difficult control portion during the whole system. In the coiling part, the control technology are commonly used the synchronous control and tension control for realization of metal winding; Line: line of metal wire, for the whole wire drawing machine, the control has no high accuracy requirements, to the majority of wire drawing machine, the line operation is through the inverter to drive line frame to achieve, but there are also drawing mechanical parts of dual frequency conversion control, or even directly through the drawing wire tension wire link to drawing machine, to realize the free line. Lapping is the removal of material to produce a smooth, flat, unpolished surface. Lapping processes are used to produce dimensionally accurate specimens to high tolerances (generally less than 2.5 μm uniformity). The lapping plate will rotate at a low speed (

Level Switches
Описание: Level Switches What is a Level Switch?A Level Switch is an electrical or mechanical method for measuring the level of a liquid, powder, or granule material. It is designed to activate an alarm if the material level in a container passes a predetermined height or depth. When a level switch detects that a tank is full, it is referred to as full or upper limit detection. If the level of the material drops, indicating that the tank is nearly empty, the switch will also provide an alert, which is referred to as empty or low level detection. Level switches are an essential part of production operations and are used in harsh conditions where there are extremes in temperature, pressure, and vibrations. The diversity of level switches makes them applicable to any conditions for measuring a wide array of products. Their accuracy, reliability, and durability are a necessity for the efficiency of industrial applications. What is a Liquid Level Gauge? A liquid Level Gauge, also known as a level indicator or sight glass, is a meter that is used to determine liquid level in a process tank, vessel or drum. A level gauge is simply a glass tube that gives a visual representation of the level of liquid that is in the vessel. While simple in their design, they are a very effective technology for a direct visual indication of process fluid level. There are many applications across the industry that require the monitoring of the liquid level and there are many different types of level indicators to fulfill these varying needs. In many situations the fluid is dangerous or the place in which the liquid is stored is of such a nature that it is manually impossible to find the level, making some sort of level indicator imperative. Liquid Level Transmitters are used to monitor and regulate levels of a particular free-flowing substance within a contained space. These substances are usually liquid, however liquid level sensors can also be used to monitor solids, such as powders. There are many different types of liquid level sensors, and they have several uses, both industrial and in the household for example. Liquid level sensors are widely used industrially. Cars use liquid level sensors to monitor a variety of liquids, including fuel, oil and occasionally also specialist fluids such as power steering fluid. Liquid level sensors can also be found in industrial storage tanks, for slurries, and water level sensors can even be found in household appliances such as coffee machines. Basic liquid level sensors can be used to identify the point at which a liquid falls below a minimum or rises above a maximum level. Many liquid level sensors can detail the specific amount of liquid in a container relative to the minimum/maximum levels, to provide a continuous measurement of volume. A Flow Meter (or flow sensor) is an instrument used to measure linear, nonlinear, mass or volumetric flow rate of a liquid or a gas. When choosing flowmeters, one should consider such intangible factors as familiarity of plant personnel, their experience with calibration and maintenance, spare parts availability, and mean time between failure history, etc., at the particular plant site. It is also recommended that the cost of the installation be computed only after taking these steps. One of the most common flow measurement mistakes is the reversal of this sequence: instead of selecting a sensor which will perform properly, an attempt is made to justify the use of a device because it is less expensive. Those "inexpensive" purchases can be the most costly installations. This page will help you better understand flow meters, but you can also speak to our application engineers at anytime if you have any special flow measurement challenges. When left unmonitored, several of the gases emitted in research and industry can pose significant explosion, asphyxiation, or poisoning risks. The first line of defense against these invisible threats are Gas Detectors, but it can be challenging to understand which type of detector to employ for a specific application. A wide range of gas detection hardware is available on the market, from portable single-gas detectors to fixed sensor arrays that can precisely monitor huge quantities of different gases at the same time (known as multi-gas or multi-component detectors). Gas hazards can be generally categorized as either toxic, combustible, or asphyxiating (where the body is deprived of oxygen). Researching the possible gas hazards in a specific application is an integral part of ensuring the safety of personnel in wastewater treatment plants, petrochemical processing facilities, and a range of additional industries. After specific gas hazards have been determined in a particular environment and all potential measures have been put in place to reduce the risk of dangerous gas accumulation or gas leaks, companies must remain vigilant. Both fixed and portable gas detectors are important life-saving devices that should be correctly used in any environment that may pose a gas riskA Pressure Transmitter is a mechanical device that measures the expansive force of a liquid or gaseous sample. Also known as a pressure transducer, this type of sensor is typically composed of a pressure sensitive surface area made of steel, silicon, or other materials depending upon the analyte’s composition. Behind these surfaces are electronic components capable of converting the applied force of the sample upon the pressure sensor into an electrical signal. Pressure is generally measured as a quantity of force per unit of surface area, and is expressed as the value required to stop a liquid, gas, or vapor from expanding. Various derived units are used to quantify pressure, including: As a proportion of / relation to a pascal (Pa), or a single newton per square meter (1 N/m2); A value of pounds per square inch (psi).Pressure sensitive environments such as the gas, petrochemical, laboratory, and pharmaceutical industries often require pressure transmitters to monitor the applied force of liquids and gasses as a value of either Pa or psi. This necessitates the precise integration of pressure transmitters into rapid electrical conversion equipment, to ensure results are accurate and delivered in real-time. A Flow Switch, like all switches, is a device designed to make and break an electric current in a circuit. In an industrial system, a flow switch is essential in monitoring and controlling the flow rate of process media – such as steam, liquids, and gases. Flow switches help maintain safe and manageable rates of flow by triggering actions in various machines within a system to provide on/off flow control of process media. As previously stated, flow switches are used to monitor and control the flow rate of fluid within an industrial process system. Automated industrial systems that process fluid media rely heavily on flow switches to ensure safe and optimal flow rates. Flow switches respond to pre-set flow rate levels and perform two functions when those levels are reached: namely, closing its contacts and turning a specific piece of equipment ON, or opening its contacts and turning a specific piece of equipment OFF.

Uses Of Battery Uses
Описание: Uses Of Battery Uses of Battery Cell include providing backup power during a power outage. At home, the batteries are typically wired to electrical appliances. If the power goes down, these appliances still receive power. For example, many customers have energy rates that change based on the time of the day. Batteries can help these customers manage their energy by storing energy during low-cost times and discharging energy during high-cost times. Batteries can store energy from solar and wind and discharge it when it is needed the most. In this article, let us study the applications and uses of batteries. Applications of BatteriesBatteries are small essential components to operate many devices. It is one of the key components in our day-to-day life. Wheels Battery is a rechargeable battery and is used in each and every sector. Below are some of the applications of batteries. Disposable batteries power things like remote controls, torchlight, etc. Rechargeable batteries such as alkaline batteries are used in digital cameras, handheld video game consoles, cellphones, and many more. Advanced batteries like lithium batteries power appliances draw too much power, example: laptops and other devices. Battery Use in Health InstrumentsArtificial limbs, hearing aids, insulin pumps, valve assistance devices use batteries. Mercury batteries can be useful for photographic light meters and electronic devices such as real-time clocks in appliances. Battery Use in Medical SectorECG heart monitor is hooked up with a battery so that it can be moved with the patient and is always ON for showing the patient’s vitals. In hospitals, rechargeable batteries such as lithium-ion batteries and nickel-cadmium batteries are used. Battery Uses in Logistics and Construction Heavy-duty batteries are used to power devices such as forklift because exhaust fumes and carbon monoxide while combustion might prove dangerous in confined work areas. The lead-acid battery is used for starting, lighting, and ignition of automobiles. Battery Use in Firefighting and Emergency Response Batteries are used in radios which is very important for emergency response. These radios use large batteries in order to hold large charges. ECGs, flashlights, and even metal or fire detectors use batteries. Every day these devices help to save lives. Batteries Uses in Military OperationsBatteries power the radios which are used to communicate. Even infrared goggles are powered by batteries. Lithium provides much longer life to devices, and silver oxide batteries are used in military and submarines. Batteries Use in VehicleElectric-Vehicle Battery (EVB) is commonly used in vehicles. This E-Vehicle Battery is used to power the electric motors of electric vehicles. The batteries of electric vehicles are usually rechargeable. Generally lithium-ion batteries are used in electric vehicles. Lithium futureThe first challenge for researchers is to reduce the amounts of metals that need to be mined for E Vehicle Lithium Battery. Amounts vary depending on the battery type and model of vehicle, but a single car lithium-ion battery pack (of a type known as NMC532) could contain around 8 kg of lithium, 35 kg of nickel, 20 kg of manganese and 14 kg of cobalt, according to figures from Argonne National Laboratory. Analysts don’t anticipate a move away from lithium-ion batteries any time soon: their cost has plummeted so dramatically that they are likely to be the dominant technology for the foreseeable future. They are now 30 times cheaper than when they first entered the market as small, portable batteries in the early 1990s, even as their performance has improved. BNEF projects that the cost of a lithium-ion EV battery pack will fall below US$100 per kilowatt-hour by 2023, or roughly 20% lower than today (see ‘Plummeting costs of batteries’). As a result, electric cars — which are still more expensive than conventional ones — should reach price parity by the mid-2020s. (By some estimates, electric cars are already cheaper than petrol vehicles over their lifetimes, thanks to being less expensive to power and maintain.) In order to make lithium-ion batteries cheaper, scientists at Pennsylvania State University in the US are looking at lithium iron phosphate batteries, which use different electrode elements. This E Tricycle Lithium Battery model is much cheaper and safer than the widely used lithium nickel manganese cobalt oxide batteries, and has the potential to power a car 250 miles on as little as ten minutes’ charge. Anxiety around the range fully charged EVs can cover is also driving carmakers to develop batteries that use a solid component that separates the electrodes, rather than a liquid one. These are safer and can power EVs further than 300 miles on a single charge. But lithium batteries have a problem. Lithium is a relatively rare element on Earth compared with most minerals in common use. As demand for batteries increases, the price of lithium will increase sharply. This has prompted geologists to search for new sources of lithium worldwide, often with their own high costs. For example, the extraction of lithium from salt flats in Chile consumes lots of water, which is in short supply there. Cobalt is also scarce compared with similar metals like iron, and ores are concentrated in the politically unstable Congo region of Africa. One solution may be to get more use out of what we already have. With more than a million electric cars sold worldwide in 2017, a number increasing rapidly, scientists are studying how to recycle lithium on a massive scale. Some are considering whether bacteria could help them achieve this. In future, it will be important to design Energy Storage Battery that can be easily disassembled, to reuse the metals they contain. Lithium is also a very reactive metal, presenting challenges for people tasked with handling it. There are also potential alternatives to lithium. For example, sodium-ion batteries are gathering interest from EV manufacturers due to their lower cost. They work similarly to lithium-ion batteries but sodium is heavier and stores less energy. Somewhat further into the future are multivalent batteries, where the ion that moves between electrodes has a greater charge than lithium and so delivers more than one electron each to the circuit. There are substantial challenges for scientists to overcome with these batteries, but they could potentially deliver even higher energy storage. Building enough electric cars at a price that will make them cheaper than fossil fuelled alternatives is a major challenge. At the fore of battery research, scientists are working to solve this problem and revolutionise how we travel.

How LED Streetlights Work
Описание: How LED Streetlights Work Amidst all the hubbub about tackling global warming and cultivating green energy, one subject receives little coverage: streetlights. While an important public service, streetlights are expensive to maintain and taken together, suck down a lot of energy. So when a city like Los Angeles announces that it's converting 140,000 streetlights to light emitting diodes or LEDs, and Pittsburgh states that it's considering doing the same with 40,000 lights, it's time to take notice. LEDs are gaining traction as a great alternative to traditional lighting because they are relatively environmentally friendly, don't consume much electricity and have long life spans. They last so long -- 14 years or more in some cases -- that they can be considered "semi-permanent" In the past, LED lights had been seen in devices like indicator lights in appliances, calculators or in large sports scoreboards. But now, many large cities around the world -- Los Angeles, San Francisco, Toronto and Tianjin, China, to name a few -- are now switching to LED Street Light. Portugal is in the midst of a massive conversion program that is expected to encompass all of its streetlights. Advantage of LED Streetlights Chief among the advantages of LEDs is that they have extremely long lives -- they don't have filaments that can quickly burn out -- and they don't contain toxic chemicals like mercury, unlike traditional high-pressure sodium lamps or mercury-vapor lamps. An LED light can last 100,000 hours. These lights also have reduced maintenance costs because of their long lives, and they give off less heat than other bulbs. Because they last so long, LEDs are suitable for places where replacing light bulbs is expensive, inconvenient or otherwise difficult. LEDs are highly energy efficient. While compact fluorescent lamps (CFLs) recently have been touted as the standard in green lighting, LEDs actually have double their energy efficiency. They use 15 percent of the energy of an incandescent bulb while generating more light per watt. LEDs produce 80 lumens per watt; traditional streetlights can only muster 58 lumens per watt. Because of their energy efficiency and long lifespan, LED Module Street Light is advocated as a means for reducing carbon emissions. According to one estimate, converting all American light fixtures to LEDs would halve the amount of energy used for lighting in the country. By integrating solar panels, the lights can become self-sufficient and even send excess energy back to the grid, with the adoption of so-called "smart" energy grids. Solar Street Lights are powered by photovoltaic panels, meaning they produce clean and sustainable energy. When choosing to rely on solar energy for public lighting projects, local authorities can effectively reduce their energy consumption as well as their carbon footprint. By doing so, they limit their environmental impact and play an active part in the energy transition, in line with national and global energy policies. But there’s more to it. Adopting solar lighting solutions helps preserve biodiversity in areas that are the most sensitive to light pollution. Solar street lighting systems adjust the intensity of the light over the course of the night through the use of dynamic lighting profiles, making street Lighting Pole more respectful of living ecosystems – especially birds, whose migratory behaviour is strongly affected by light pollution. More generally, it’s important to consider the key role played by lighting in the creation and flourishing of communities. Quality solar lighting offers citizens a better experience of the city. It helps improve the readability of public space, thus making it more accessible and welcoming. It acts as a driver of social cohesion, strengthening the ties and interaction between individuals, while allowing them to carry on their social and recreational activities throughout the evening. Installing All in One Solar Street Lights provides an opportunity to extend parks night-time opening hours or promote access to outdoor sports facilities. In addition to encouraging people to visit public places after dark, it also improves their safety. On rural roads or cycling paths, the presence of solar lighting solutions helps promote better traffic flow and reduces accidents. Cities face major challenges: demographic growth, urban concentration, mobility, the evolution of citizens’ needs... To meet these, public stakeholders need technological innovations they can trust and rely on to rethink and transform the existing public space, with the aim to make cities smart and sustainable. At the heart of smart cities, street furniture is undergoing digital transformation to be able to generate information. This is the case for solar-powered Garden Lights, which are evolving to integrate and power various communication equipment and intelligent applications (billboards, interactive terminals, advertising displays, Wi-Fi hotspots…). An example of this is our RISE-On range, a smart solar engine that powers all outdoor electrical equipment in cities. While access to electricity is growing globally, more than 11% of the world's population still lives off-grid, according to the International Energy Agency (IEA). This figure rises to 46% in Africa, in particular in sub-Saharan Africa where nearly 600 million people live without access to electricity. Providing off-grid populations with access to energy plays a crucial role in accelerating their economic development, reducing inequalities and improving their security, in addition to having a positive impact on education and schooling. Deploying solar Flood Lights on a city’s main roads, streets and in other public places makes them easier to access, supports businesses and improves social ties. Additionally, in more isolated areas, these lighting solutions help reduce insecurity, theft and assaults. They have a particularly strong impact in sensitive areas such as refugee camps, where the lack of lighting leads to serious crime. Replacing oil or kerosene lighting systems with solar-powered solutions also helps create a healthier environment that improves the health and well-being of the community.

What Are Laminate Floors?
Описание: What Are Laminate Floors? Once installed mainly as a type of economy flooring, Laminate Flooring still firmly holds its place as inexpensive, functional flooring. But they have even moved into higher-end homes that once would have installed nothing but solid hardwood or engineered wood flooring. Laminate floors look better, perform better, and feel better underfoot than ever before. All of this popularity may beg the question: What are laminate floors in the first place? Basics of Laminate Floors Laminate floors are a hybrid floor covering consisting of a particleboard wood base topped by an image layer and a transparent wear layer. Laminate floors are a popular type of floor covering for homes' living areas, kitchens, dining areas, bedrooms, hallways, and other areas that are not subject to excessive moisture. HDF Laminate Flooring was invented in 1977 by the Swedish company Perstorp. This firm landed on the idea of using up waste wood projects by subjecting those products to intensely high pressure, heat, and binding chemicals, then turning the result into usable floor coverings. Since that time, many other manufacturers such as Dupont, Mannington, Armstrong, and Shaw now make laminate floors. Laminate Floor Materials Laminate floors are sometimes called laminate wood floors, though they are wood only in two respects. First, the laminate floor base consists of pressed chipped wood particles. Second, the top has the appearance of real wood due to the accurate image layer—essentially a well-rendered photograph of wood encased in a clear, durable wear layer. Aggregated wood particles are subjected to high pressure to form sheets. These sheets have a photorealistic image of wood or stone added to the top, and this image is covered with a wear layer. The wear layer, a durable, thin, clear plastic sheet, is the linchpin between the delicate lower layers and exterior elements such as moisture, UV rays, and scratching. Wear Layer: MDF Laminate Flooring is a surface layer of two thin sheets of paper impregnated with melamine. This top-most surface layer is a hard transparent type of plastic sheet that is impervious to dogs, chairs, high heels, and other common damaging elements. Image Layer: Even when viewed close-up laminate flooring can look realistic. This is due to the laminate's photographic-quality image of real wood underneath the wear layer. Base Layer (Core): Under the wood-grain photograph is about a half-inch of wood-chip composite. Any type of wood chip product is inherently susceptible to water damage. Laminate flooring's base is considered to be dimensionally stable, but only to a certain degree. It will stand up against some water, but only if this water is quickly removed. What Is Vinyl Flooring? Vinyl Flooring is a type of synthetic flooring that provides great benefits and it is extremely versatile. It is somewhat similar bares similarities to linoleum flooring and is considered one of the most popular choices in wet areas such as bathrooms and cooking areas. They are made of polyvinyl chloride (PVC) along with a few other compounds added to allow them to have the desired hardness, whilst still being flexible. The top layer is made up of a urethane-based coating. It provides durability and stability because of its water-resistant and stain-resistant properties. In recent times, companies have been trying to improve the safety and econ-friendliness of vinyl floorings, where they try to materials that are organic and do not emit harmful chemicals. Improvements over the years have resulted in a variety of attractive, economical, and affordable that give you countless ways to fit your choice to other elements of your interior design. Now there are newer and improved versions which include luxury vinyl tiles (LVT) and luxury vinyl planks (LVP). They come under the umbrella term called luxury vinyl flooring (LVT). It has many variations which include dry back (waterproof and has thermal stability), loose lay (no need for adhesives due to heavy back of fiberglass) and, PVC click (utilizes a click system). Another type lesser-known type is known as vinyl composition tile (VCT) which contains limestone powder to increase its durability. It contains lesser amounts of vinyl but in the long run, it requires higher and more continuous maintenance. What makes Vinyl Flooring so popular and unique? Let us take a look at why vinyl flooring is in demand – not only in housing areas but in commercial and industrial places as well. Vinyl SPC Flooring has a top layer of protection formed by Tuff Shield technology. This technology serves to safeguard the vinyl floor and allow it to resistant to scratches. This contributes to the vinyl flooring’s durability and allows it to maintain its longevity for a long time 2. Dimensional StabilityNow let’s delve into the insides of the vinyl flooring. The middle layer is what provides the stability that allows for the installation of the flooring.This dimensional stability is what helps the material to retain its original shape, especially when it has been subjected to harsh environmental changes, 3. Locking Mechanism for ease of installation Lastly, the locking mechanism that the vinyl planks have allows for the flooring to stay locked against each other when it has been installed. This prevents it from opening up or for moisture to seep into the flooring quickly, making it highly durable, and water-resistant.

Are Sustainable Hangers All They’re Cracked Up To Be?
Описание: Are Sustainable Hangers All They’re Cracked Up To Be? What’s the problem?The sad reality is that 85% of hangers end their life in landfill. In the US, everyday over 15.5 million plastic, wood and wire hangers are thrown away, resulting in 8 billions every year. In the UK 100 million Plastic Hangers are discarded each year. So, what is the industry doing about it? Brands are starting to get to grips with this challenge and are looking at ways of replacing hangers, particularly those pesky plastic ‘garments on hangers’ otherwise known as GOH (garments transported on hangers from factory to store) that are made from plastic and represent a huge part of the overall volume of hangers discarded each year. Made predominantly from expanded polystyrene, or polycarbonate, plastic hangers not only depend on fossil fuels for their raw material and production but take an estimated 800-1,000 years to breakdown. They also leach nasty chemicals including carcinogenic benzene, found in polystyrene and Bisphenol-A, a hormone disrupter, into groundwater. They can also cause havoc for wildlife; with animals getting hangers caught around their necks, legs and wings. Plastic waste is pantsRemoving hangers should always be the first step. Does underwear need to come on Plastic Clothes Hangers? Customers don’t think so, going by some tweets that made the headlines in the UK. After receiving underwear in the post from British retailer Marks & Spencer, one customer exclaimed “What on earth is anyone supposed to do with these?” while another said “Just had some undies delivered and each one came on an unnecessary, plastic, individual hanger. Lovely items, but when will you stop this wasteful practice?”. For a long time, most (if not all) cutting boards were made of wood. But at some point people began using plastic cutting boards. The idea was that they were easier to clean (and sanitize), and therefore were safer.But in the late 1980s, a UC Davis researcher named Dean Cliver – the de facto godfather of cutting board food safety – decided to investigate whether plastic cutting boards really were safer. Answer: not really. Plastic Chopping Boards, Cliver found, are easier to sanitize. But cutting on them also leaves lots of grooves where bacteria can hide. Wood is tougher to sanitize, but it’s also (often) tougher in general – you won’t find as many deep scratches in the surface. In addition, researchers have discovered that the type of wood your cutting board is made from also makes a difference. “Hardwoods, like maple, are fine-grained, and the capillary action of those grains pulls down fluid, trapping the bacteria – which are killed off as the board dries after cleaning,” says Ben Chapman, a food safety researcher at NC State. “Soft woods, like cypress, are less likely to dull the edge of your knife, but also pose a greater food safety risk,” Chapman explains. “That’s because they have larger grains, which allows the wood to split apart more easily, forming grooves where bacteria can thrive.” Portable Plastic Drying Racks are a great option for small apartments and homes where there is no outdoor space to air-dry clothing items. As Air drying is one of the safest techniques for drying most clothes, a drying rack is a must in every home. These racks come in a variety of shapes and sizes along with folding and expanding mechanisms that make them truly versatile. Depending on personal preference, users also choose the materials of the rack as designs are available in wood, steel, aluminium, plastic and acrylic. For outdoor drying like a palcony, materials that can withstand the scorching sun for a long time are preferable. For drying clothing y oors, plastic and acrylic racks would work too. For burchasing the perfect drying rack for your home, consider the number of clothing you will be drying at once. For a heavy load, sturdy design is a must. Residents living in space crunched apartments can opt for a wall-mounted design that serves the ourpose without hogging floor space. Plastic Preservation Boxes can be used for the storing of a wide array of different items, and storing clothing and other important items in plastic storage containers is a good way to prevent them from being exposed to mildew and moisture. If any moisture gets into a plastic storage container prior to sealing it closed, however, then mildew can grow and thrive without you being any the wiser. In this article we will outline a few simple steps that will help prevent mildew from growing in your plastic Food Storage boxes. It is extremely important to make sure that your items are clean and dry before storing them away. Any dirt left on your belongings can easily cause scratches if left on for too long. Clothing and upholstery that get put in storage while damp can attract mould and moisture, and metals and woodwork can rust or rot. Properly cleaning and drying all of your items before storing them will prevent this from happening. Melamine is a nitrogen-based compound used by many manufacturers to create a number of products, especially plastic dishware. While melamine is widely found in many items, some people have raised safety concerns that the compound could be toxic. Is it safe? The short answer is yes, it’s safe. When manufacturers create plasticware with melamine, they use high heat to mold the substances. While the heat uses up most of the melamine compounds, a small amount does usually remain in the Plastic Dinner Plates, cup, utensils or more. If melamine gets too hot, it can start to melt and potentially leak into food and drink products

What are fluoroplastics and why use them?
Описание: What are fluoroplastics and why use them? Fluoroplastics may not be widely known, but in many ways, they are the superheroes of the plastics industry, and incredibly strong. What are fluoroplastics?A normal plastic polythene molecule consists of a carbon chain with hydrogen atoms attached. Yet in fluoroplastics, hydrogen atoms are replaced with fluorine atoms, which dramatically changes their properties. PTFE, FEP, PFA and other fluoropolymers have non-stick characteristics, very high resistance to chemicals and solvents, very high electrical resistance, and incredibly, are ideal for use in very low and very high working temperatures from -200°C right up to +260°C. By adding extra fillers to the mix, such as carbon, graphite, anti-static and ceramic, it is possible to boost these exceptional properties even further! Find out more about our Fluoroplastic Tubes. Fluoroplastic applicationsTypically, fluoroplastics do not melt, so they need to be processed using special tooling and techniques. But once this is done, there are many different industries that PTFE, FEP and PFA can be used into great effect. Being able to function in extremely high temperatures and non-corrosive to all acids, fluoropolymers are often used to make gaskets, vessel linings, pump interiors, washers, rings, seals, spacers, dip tubes and well-drilling components. Fluoroplastic Films are well used in heated processes within manufacturing and laboratory test environments. In electrics, they are used as excellent insulators for wire and cable wrapping. Being inert, they can be used for chip manufacturing and encapsulating heaters. Their non-toxic, completely smooth surface means that they are also often used in the medical and pharmaceutical, food and drink, and cosmetics industries, as microbes just cannot gain a foothold.Silicone Rubber comes in a variety of forms, adhesives, sealants, moulding rubbers for reproduction, encapsulants and potting compounds for electronics and coatings. Silicone polymers are usually flowable liquids which are cured to form a flexible silicone elastomer or rubber. Additives provide additional characteristics such as adhesion, colour, thermal conductivity to mention a few. Silicone rubber is especially resistant to high temperatures and attack from moisture or chemicals. As silicone sealants they are widely used in the construction industry with excellent adhesion to glass and ceramics and plastics.In electronics they are used as adhesives, encapsulants and coatings providing high temperature resistance and being increasingly used for thermal transfer in high power or heat generating applications. What is Viton? Viton Rubber is a brand name of DuPont for its synthetic rubber and fluoropolymer elastomer, commonly used in O-rings and other molded or extruded products. This family of elastomers comprises copolymers of terpolymers of tetrafluoroethylene (TFE), hexafluoropropylene (HFP) and vinylidene fluoride (VDF or VF2), vinylidene fluoride (VDF) and hexafluoropropylene (HFP) as well as perfluoromethylvinylether (PMVE) containing specialty polymers. DuPont were the first to really market this family of materials, so Viton has become the most commonly associated name with this fluoropolymer family. There are four families of Viton polymers, and the fluorine content of these most popular Viton grades varies between 66 and 70%. The main grades are A (Dipolymers of VF2/HFP), which has a fluorine content of 66%; B (Terpolymers of VF2/HFP/TFE), which commonly used for seals or gaskets and contains 68% fluorine; F (Terpolymers of VF2/HFP/TFE), which is used in oxygenated automotive fuels and has 70% fluorine content; and finally specialty types (such as GLT, GBLT, GFLT & Viton Extreme), which are used in automotive and oil exploration applications. Silicone Sponge Products have swept into kitchens but what’s so great about them and should you buy a silicone sponge? If you ever get fed up with the smell of your kitchen sponge, you should probably get rid of it. But that’s only a temporary fix because your sponge is eventually going to smell at some point. So how do you get a sponge that won’t smell? One popular solution is a silicon sponge. Does a Silicone Sponge Work With Dishes?A silicone sponge is not porous, like a typical sponge, so it’s less susceptible to bacteria taking root. Bacteria makes sponges smell so a silicone sponge eliminates that problem. Benefits of a Silicone SpongeSilicone sponges get touted as being environmentally friendly because they reduce the consumption of cellulose sponges and will last far longer. Plus, you can wash the sponge in your dishwasher and it won’t scratch your pots and pans. A silicone sponge is also great for other things like picking up lint and pet hair. Sponge rubber can be designed to be open cell or closed cell, but is most commonly used as closed cell and is also known as expanded rubber. Inside a piece of sponge rubber, there are enclosed capsules, or cells, that do not connect with each other. They look very similar to the “bubbles” in a piece of extremely dense foam. These cell walls are useful for preventing water, air, and to some extent sound from passing through the material. Closed cell sponge rubber can be modified to embody various products necessary to make it suitable for a specific application. Closed cell EPDM Sponge Products offer great ozone resistance and stand up well to adverse weather conditions. However, it is vulnerable to certain fuels and oils and may fall short of UL flame ratings unless a suitable additive is added to improve its flame-retardant qualities. Closed cell silicone sponge rubber is stable at both high and low-temperature extremes. It’s characteristically less flame-resistant than many other closed cell sponge rubbers but does offer excellent sunlight and ozone degradation resistance. Neoprene Sponge Products are designed to be more flame resistant than many of their counterparts. It can withstand intermittent exposure to temperatures of up to approximately 90°C, and with careful compound manipulation can resist light oil contact, acids, alkalis, and ozone damage. These are by no means the only types of closed cell sponge rubber, but they are certainly some of the most common. What is Plastic Tubing? Plastic tubing is a form of tubing that is manufactured from a mixture of a polymer with a variety of chemicals to form a material that can be solid or flexible. Since its first use in the 1950‘s, Plastic Tube has revolutionized industrial processes and has found a use in a wide variety of applications. The popularity of plastic tubing is due to its adaptability and flexibility. It is produced in a wide variety of wall thickness, diameter, tolerance, and strength using a combination of materials to specifically fit a variety of applications. Applications for Plastic TubingThe flexibility, durability, and adaptability of plastic tubing makes it applicable for industrial applications that require long wear and endurance as well as commercial use in consumer products and homes. The main benefit of plastic over steel, aluminum, or other materials is its consistent strength and cost effectiveness since it is far less expensive to produce.

Nitrile vs Vinyl Gloves - A Detailed Comparison
Описание: Nitrile vs Vinyl Gloves - A Detailed Comparison What are the differences between nitrile vs vinyl gloves? Which is better for what purposes?While nitrile gloves are generally more expensive than vinyl gloves, they offer a number of advantages over vinyl. When choosing disposable gloves, the main issue to consider is which ones are appropriate for the task at hand. The purpose of this guide is not to give you a definitive answer on which type of glove is better. Rather, it will provide information about nitrile and vinyl gloves that allow you to make your own decision based on your needs. What are Nitrile Gloves?Nitrile is a synthetic rubber that offers flexibility, long-life durability, and chemical resistance. Nitrile is a synthetic elastomer designed to be moisture resistant. Disposable nitrile gloves are flexible and durable making them ideal for industrial tasks, the food industry, and health care applications. They are also great for most medical environments. What are Nitrile Gloves Made From?Nitrile Gloves are made from synthetic rubber called acrylonitrile-butadiene rubber. This material provides users with heightened tactile sensitivity, allowing you to pick up small items such as screws and needles more accurately. They are also more puncture resistant. The disposable glove materials were first developed to solve the common problems of allergic reactions to natural rubber latex gloves and low protection against solvents. They are the most popular glove materials used in many industries and the ideal alternative to disposable latex gloves. What are Nitrile Gloves Used For?Nitrile gloves are used for a variety of industrial, domestic, and healthcare purposes. Nitrile gloves are the popular choice for health care workers, dentistry, beauty shop owners, healthcare providers, laboratory work, food handling, chemical handling, and general industrial tasks. Nitrile protective gloves can also be found in the automotive industry and janitorial industry. Nitrile was found to be more durable than vinyl when performing gripping tasks with power tools and picking up tools like wrenches and screwdrivers. What are Vinyl Gloves? Vinyl Gloves are also made of a synthetic polymer but are often less thick and, as a result, less durable. Vinyl is great for non-hazardous situations but does not have the flexibility of nitrile. What are Vinyl Gloves Made From Vinyl gloves are made from a blend of synthetic rubber, plasticizers, and additives called PVC. They were also developed as a great option for those suffering from latex allergies. What are Vinyl Gloves Used For? Vinyl gloves are frequently used for food handling, food preparation, low-risk health care applications, light clean-up jobs, and repetitive assembly line or manufacturing tasks. These products are commonly used in non-hazardous situations and low-risk infection environments because of the low level of protection offered. They work great for the food and beverage industry. For decades, latex gloves were the king of the disposable glove industry. These days, though, as latex allergies are increasingly common, latex products have a more niche application. Either way, the material remains well-suited to handling certain jobs--and ill-suited to others. Not sure whether latex gloves are the right fit? Here’s a look at what latex gloves are used for. What are Latex Gloves?You might be surprised to learn that the materials behind Latex Rubber Gloves are naturally occurring. In fact, while dip-molded latex might lead you to believe these are purely synthetic gloves, latex is actually a naturally occurring plant material. Basically, latex is any polymer in a water-based or viscous form. Natural latex, or natural rubber latex, is derived from the rubber plant Hevea brasiliensis and is a complex emulsion of proteins, sugars, oils, starches, tannins, alkaloids, resins, and gums that coagulate when exposed to the air. We transition from the rubber plant to commercial latex by taking fresh latex and transforming it through a process of blending, coagulation, and drying. What are Disposable Latex Gloves Used For? Latex gloves have long been popular power players among disposable gloves, whether they’re powdered latex gloves or powder-free gloves. These days, workplaces are more conscious of latex allergies. Even so, latex remains a popular glove material for its comfort, stretchiness, and tactile sensitivity. This makes latex a popular compound among a specific population: the medical industry. In terms of medical gloves--especially surgical gloves--few materials can match the dexterity and tactile sensitivity of a latex glove. This is incredibly important for work requiring extreme precision, such as surgery. That said, even regular physicians remain frequent users of latex gloves. Even a regular physical exam needs tactile sensitivity, and on that front, latex gloves are hard to beat. Latex is also quite popular among workers who need frequent glove changes, whether that’s the healthcare industry or elsewhere. In many cases, you would need powdered gloves to provide the same comfort level as latex powder-free gloves. POLYETHYLENE GLOVES are our most economical glove. PE Products are most often used for light duty tasks that require frequent glove changes. This glove has a loose fit design for easy on and off applications, and is especially useful in food service lines, deli counters, and other high volume applications. Our clear PE Gloves are available in high density, low density, cast poly, and a new stretch hybrid version that is also available in blue. All PE gloves sold by The Safety Zone are powder free and non-medical as well. All Poly Gloves are 100% Phthalate Free, 100% Latex Free and 100% Silicone Free.
